I am trying to update the rows of the below html table dynamically based on the input received from ajax request made which returns a JSON object.
If i get more than one json object it bees an issue to print it on the web page. I am looking at possible best solutions in this case to dynamically update my table using jQuery? For example If i get 10 objects I only want to show 5 and the rest maybe a next page link ? Can someone guide me what should i look into ?
jQuery Ajax
<script>
$.ajax({
url: 'http://localhost/getData/USSOUTH/',
async: false,
dataType: 'json',
success: function(data) {
for (var i in data) {
var USERNAME = data[i].USERNAME;
var EMAIL = data[i].EMAIL;
var PASSWORD = data[i].PASSWORD;
var ACTIVE = data[i].ACTIVE;
}
}
});
</script>
HTML BODY
<body>
<div class="wrapper">
<div class="table">
<div class="row header blue">
<div class="cell">
Username
</div>
<div class="cell">

- If you only want the next 5 entries, why not include that parameter in the request, and have it return just those? Or add them all, but hide the last 5, and include a button to show them? – Matthew Rapati Commented Jan 20, 2015 at 21:05

Reset to default 3i kinda simplified the code, but you'll get the gist and can modify it to apply with your specific code (and i cant do json with code snippet, so i simulated an array variable called jsonData)
$(document).ready(function() {
var jsonData = [
{ 'name': 'name2', 'email':'email2', 'content':'content2' },
{ 'name': 'name3', 'email':'email3', 'content':'content3' },
{ 'name': 'name4', 'email':'email4', 'content':'content4' },
{ 'name': 'name5', 'email':'email5', 'content':'content5' },
{ 'name': 'name6', 'email':'email6', 'content':'content6' },
{ 'name': 'name7', 'email':'email7', 'content':'content7' },
{ 'name': 'name8', 'email':'email8', 'content':'content8' }
];
$('.add').on('click', function() {
console.log('click');
var length = jsonData.length;
if (length > 5 ) { length = 5; } //limit to 5
for (var i = 0; i < length; i++) {
var clone = $('#template').clone(true).attr('id', '');
clone.find('.name').html(jsonData[i]['name']);
clone.find('.email').html(jsonData[i]['email']);
clone.find('.content').html(jsonData[i]['content']);
clone.appendTo('table');
}
});
});td {
border:1px solid black;
padding:2px;
}<script src="https://ajax.googleapis./ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<a href="#" class="add">add</a>
<table>
<tr id="template" class="dataRow">
<td class="name">Name1</td>
<td class="email">Email1</td>
<td class="content">Content1</td>
</tr>
</table>You can check the AJAX service documentation if it supports paging, which is its respond will contain only 5 records and an indicator that there is some more. That way you will be able to request next 5 records to display if needed in similar way as your first request.
If the service does not support paging then you may hide any record above first 5, with attribute style="display: none;" and display navigation links NEXT & PREVIOUS to "scroll" results.
// Data will be replaced with your Json call
var data = [
{'username': 'name1', 'email':'email1', 'password':'password1', 'active':'active1' },
{'username': 'name2', 'email':'email2', 'password':'password2', 'active':'active2' },
{'username': 'name3', 'email':'email3', 'password':'password3', 'active':'active3' },
{'username': 'name4', 'email':'email4', 'password':'password4', 'active':'active4' },
{'username': 'name5', 'email':'email5', 'password':'password5', 'active':'active5' },
{'username': 'name6', 'email':'email6', 'password':'password6', 'active':'active6' },
{'username': 'name7', 'email':'email7', 'password':'password7', 'active':'active7' },
{'username': 'name8', 'email':'email8', 'password':'password8', 'active':'active8' },
{'username': 'name9', 'email':'email9', 'password':'password9', 'active':'active9' },
{'username': 'name10','email':'email10','password':'password10','active':'active10'},
{'username': 'name11','email':'email11','password':'password11','active':'active11'},
{'username': 'name12','email':'email12','password':'password12','active':'active12'}
];
var MAX_ROWS = 5;
var totalRows = 0;
var page = 0;
$(document).ready(function() {
// display first 5 rows
var $templateRow = $('#templateRow');
$.each(data, function(i, obj) {
var $row = $templateRow.clone().removeAttr('id')
// copy data
$row.find('*[data-name]').html(obj.username);
$row.find('*[data-email]').html(obj.email);
$row.find('*[data-pass]').html(obj.password);
$row.find('*[data-active]').html(obj.active);
$('.table').append($row);
});
// Navigation part
page = 0;
totalRows = data.length;
showRows();
displayNext();
// Navigation handler
$('*[data-prev-lnk]').on('click', function(e) {
e.preventDefault();
page--;
displayPrev();
displayNext();
showRows()
});
$('*[data-next-lnk]').on('click', function(e) {
e.preventDefault();
page++;
displayPrev();
displayNext();
showRows();
});
});
function displayPrev() {
if (page > 0)
$('*[data-prev-lnk]').show();
else
$('*[data-prev-lnk]').hide();
}
function displayNext() {
var currRow = (page+1) * MAX_ROWS;
if (currRow >= totalRows)
$('*[data-next-lnk]').hide();
else
$('*[data-next-lnk]').show();
}
function showRows() {
var startRow = page * MAX_ROWS;
var counter = 0;
$('.row').each( function() {
if (! ($(this).attr('id') || $(this).hasClass('header'))) {
if (counter < startRow || counter >= startRow + MAX_ROWS) {
$(this).hide();
}
else {
$(this).show();
}
counter++;
}
});
}div.table {border: 1px solid black; display: table; width: 500px;}
div.row {border: 1px solid black; display: table-row; }
div.cell {border: 1px solid black; display: table-cell; }<script src="https://ajax.googleapis./ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<div class="wrapper">
<div class="table">
<div class="row header blue">
<div class="cell">Username</div>
<div class="cell">Email</div>
<div class="cell">Password</div>
<div class="cell">Active</div>
</div>
<div id="templateRow" class="row" style="display:none;">
<div class="cell" data-name=''></div>
<div class="cell" data-email=''></div>
<div class="cell" data-pass=''></div>
<div class="cell" data-active=''></div>
</div>
</div>
<br/><a href='#' data-prev-lnk='' style='display:none'>Previous</a>
<br/><a href='#' data-next-lnk='' style='display:none'>Next</a>
</div>Let's use thead and tbody for better usage and add button for next set of results.
HTML:
<body>
<div class="wrapper">
<button id ="nextPage" value ="Next page">
<div class="table">
<thead class="row header blue">
<div class="cell">
Username
</div>
<div class="cell">
Email
</div>
<div class="cell">
Password
</div>
<div class="cell">
Active
</div>
</thead>
<tbody>
<div class="row">
<div class="cell">
ninjalug
</div>
<div class="cell">
[email protected]
</div>
<div class="cell">
************
</div>
<div class="cell">
Yes
</div>
</div>
</tbody>
</div>
</div>
</body>
in JS assign function to button, which will display next 5 records:
var results = "";
$.ajax({
url: 'http://localhost/getData/USSOUTH/',
async: false,
dataType: 'json',
success: function(data) {
results = data;
showResults(results);
}
});
//function for showing results
function showResults(data)
{
var rows = $('tbody .row').length; // get number of already displayed records
for (i = rows; i<=from+4,i++;) //add next 5 records
{
var content = '\
<div class="row">\
<div class="cell">\
'+data[i].USERNAME+'\
</div>\
<div class="cell">\
'+data[i].EMAIL+'\
</div>\
<div class="cell">\
'+data[i].PASSWORD+'\
</div>\
<div class="cell">\
'+data[i].ACTIVE+'\
</div>\
</div>';
$('tbody .row:last').after(content);
}
}
$("nextPage").click(function(){
showResults(results);
});
